I zeroed my red dot at 50 meters instead of the recommended 25.

What can I estimate the trajectory to be at 100 with a 55 grain 5.56? The range wouldn't let me use the 25.

I ran it with your red-dot mounted 2" above bore and 3240 fps and BC of .269. At that you should be 1.1 inches high at 100 yds with a zero at 50 yards.

Depends on the height difference between your bore and scope. But you should be around an inch high at 100 yards if we're talking an AR. I always zeroed my AR with an EOTech at 50 yards because it was close to being a 200 yard zero as well. Not sure why you'd zero it at 25?

It's the Larue mount with a micro.

It's the Larue mount with a micro. Got it. I think I'd stick with the 50-yard zero if it was me. How high would you be at 100 yards with a 25-yard zero? More than an inch I think. That's the problem with a zero at a distance that short.

Curious, were you indoors? What range wouldn't let you shoot at 25?

Was outdoors at a very large range that goes up to 600.

That's the problem with a zero at a distance that short. About 4 inches. A 25 yard zero is supposed to be right on at 275, but wouldn't really call that an ideal situation. Seems like I ended up doing better for what I wanted.

This is the correct answer. Works MOP/MOD on 55/62gr loads.

Mine is zeroed at 50 as well and is just over an inch high at 100.
